MAGAZINE-HAMMER.

Specification of Letters Patent.

Patented July 2, 1912.

Application filed March 9, 1911. Serial No. 613,291.

. and State of Missouri, have invented a new and Improved Magazine-Hammer, of which the following is a full, clear, and exact description. f

The object of the invention is to provide a new and improved magazine' hammer,

which is simple and durable in construction,

easily manipulated with one hand and arranged for quickly discharging nails, tacks or like fasteners one by one, for setting the discharged fastener at the desired place on the object into which the fastener is to be driven and allowingr driving the fastener home without requiring the operator to touch or handle the fastener, and leaving one hand free for manipulating the object.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a sectional side elevation of the magazine hammer; Fig. 2 is a plan view of the same with the cover of the hollow handle swung open and the hammer head lin section; Fig. 3 is a cross section of the magazine hammer on the line 3--3 of Fig. 1; Fig. 4l is an enlarged cross section of part of the setting device; Fig. 5 is a sectional side elevation of a modified form of the magazine hammer; Fig. 6 is a plan view of the same with the cover of the handle swung open and the hammer head in section; and Fig. 7 is a cross section of the same on the line 7-7 of Fig. 5.

The magazine hammer illustrated in Figs. 1, 2, 3 and 4, has a hammer head A secured on one end of a hollow handle B having a hinged 'cover B and containing an endless belt C passing around vertically-disposed rollers D and D journaled in the hollow handle B. The rollers D and D are provided with toothed wheels DL, D3 engaging apertures C formed in the endless belt C, and the toothed wheel D3 is adapted to be engaged by a pawl E fulcrumed on a lever F pivoted at F on the handle B and eX- tending along the under side thereof so that the lever F can be readily manipulated by the fingers of the hand having hold of the handle B. Thus when the lever F is swung upward the pawl E engages the toothed wheel D3 and turns the roller D whereby a traveling motion is given to the endless belt C in the direction of the arrow a shown in Fig. 2. On the inner surface of the hollow handle B and near the top thereof directly opposite the upper edge of the endless belt C is arranged or formed a guideway B2 for supporting in conjunction with the upper edge of the endless belt C the heads G of the nails, tacks or other fasteners Gr to be driven into an object, as hereinafter more fully explained. The belt C is provided on its outer surface with vertically-disposed spacing bars C2, spaced apart to accommodate between successive bars the shank of the fastener G, so that when a traveling motion is given to the belt C then the fasteners Gr are carried along by the belt C with the heads G of the fasteners resting on the top edge of the belt and the guideway B2. At the forward end of the handle B is formed a discharge opening B3 suiliciently large to allow the head Gr of the fastener Gr to pass down, the said discharge opening B3 registering with a similar opening A formed in the hammer head A, as indicated in Fig. 1. A pushing bar I-I is adapted to engage the fastener G after the same reaches the discharge opening B3 so that the fastener is pushed off the belt C to allow the discharged fastener to drop into the tube I of the said device and which tube I is fulcrumed at I on the hammer head A and is connected by a link J with the handle lever F previously mentioned. The pusher bar I-I above described is also pivotally connected with the lever F and is guided in a guideway H attached on the handle B. Now when the lever F is swung upward a traveling motion is given to the belt C, as previously explained, the `pusher bar H is retracted, and the tube I is swung inward to register with a setting head A2 formed 0n the hammer head A, to permit of setting the nail, tack or similar fastener at the desired point on the object into which the fastener is to be driven. It is understood that the pointed end of the fastener Gr in the setting tube I projects below the bottom ofthe hammer head A, so that it can be readily Y forward end of the handle off the belt C t0 allow the said fastener to drop into the tube I. 'Ihe downward swinging movement of the lever F is limited by a suitable stop F2, as indicated in Fig. 1. In order to accomodate nails, tacks or similar fasteners of various sizes, the setting tube I is preferably provided with jaws I2 pivoted at their lower ends in the tube I and pressed toward each other by springs I3, as plainly indicated in Fig. 4. The jaws I2 have a tapering mouth and a tapering discharge end so that the head of the fastener is readily retained in the flaring mouth to permit of setting the fastener, as above described. After the fastener has been set and while the tube I is being moved upward, the jaws I2 yield sufriciently to pass the head of the article.

In the modified form illustrated in Figs. 5, 6, and 7, the belt C3 passes around rollers D7, D5, and the shaft D(s of the roller D5 is provided at its lower end with a ratchet wheel K engaged by a pawl H2 pivotally connected with a lever L fulcrumed at L on the handle B* carrying the hammer head A3. rIhe lower end of the lever L is pivotally connected with the hand lever F3 under the control of the operator, and on the said hand lever F3 is formed or secured the tube It of the setting device, which tube is normally in register with the discharge opening B5, through which the fastener G drops when pushed ofi' the belt C3 by a pusher bar E pivotally connected withthe upper end of the lever L, and adapted to engage the head G of the fastener Gr. Ihe hammer head A3 is provided with the setting head I-I under which swings the tube I4 whenever the lever F3 is swung upward so as to form an abutment for the head G of the fastener G to be set at the time. It is understood that when the lever F3 is swung upward a swinging motion is given to the lever L which by the pawl H2 and the ratchet wheel K turns the roller D5 to impart a traveling motion to the belt C3, which also passes around a ro-ller D7 journaled in the outer end of the handle Bt. When the lever F3 moves downward to its normal position the swinging motion given to the lever L causes the pusher E to pushv off the foremost fastener Gr so that the latter drops through the opening B5 into the tube I4 which carries the fastener bodily under the setting head H4 when lever F3 is swung upward.

From the foregoing it will be seen that the magazine hammer shown and described is very simple and durable in construction, can be easily manipulated with one hand with a view to quickly and accurately set nails, tacks and like fasteners, and to finally drive such fasteners home at the desired place.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:
